[quote=samc99us][quote=gahamby]What does the manufacturer recommend for a bedding compound on a carbon mast?
I like 3M 5200 but I'm bedding stainless steel fittings on an aluminum mast. I can use a heat gun to remove the fittings.
I don't like silicone that much but when I do use it I go with Permatex RTV marine or 3M marine grade.
If you're pissing water out of the bottom of the mast it's not sealed.
I did leak detection with the mast base removed and the head of the mast lower than the base. I put the garden hose in the mast and filled her up. Water spewing out of the fittings told the tale.

I like closed end rivets.
I mask out the fittings and the area around the bed down with blue tape and goop it up real good.
At last check my mast held positive pressure.I have some new fittings to install soon so I'll see how it goes for the upcoming season.[/quote]
We bed with 3M 5200. Waterproof, robust and provides additional reinforcement to the rivets.[/quote]
